Weed dynamics in fodder oat (Avena sativa L.) genotypes

A trial was conducted at Jhansi during rabi of 2012–13 to study the weed dynamics in six oat genotypes for screening of strong competitive genotypes and major associated weed flora in oat. Amongst the six oat genotypes (JHO-822, JHO-851, JHO-99-1, JHO-99-2, JHO-2000-4 and Kent) used in study, JHO-99-2 was found strong competitor due to early vigorous growth, higher plant height and drooping leaf habit and recorded lowest weed population (97) and weed intensity (21%) and highest green fodder yield (33.18 Uha). JHO-851 proved poor competitor and recorded highest weed population (248). Melilotus alba, Rumex dentatus and Chenopodium album were found major weeds associated with fodder oat. Therefore, JHO-99-2 can be recommended as a fodder variety in Bundelkhand region as it was found a strong crop-weed competitor and produced highest green fodder yield.
